SANDER FGR AUTOIKOBILES.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed January 22, '1916. Serial No. 73,632.

To all whom it may concern:

Be it known that we, Roy H. Hosn and James RAY KINesLnY, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Sanders for Automobiles of which the following is a specification.

This invention relates to sanders for antomobiles, the object in view being to provide a device of the class referred to which is bodily applicable to an automobile, motor truck or the like, the device comprising a rotary sanding head for throwing and distributing dry sand on the road way in advance of the driving wheels of the machine, combined with a motor for driving the rotary head and a reservoir containing the sand for distribution, the device also comprising a force feed element which prevents the congestion of sand in the reservoir and insures the uniform delivery of the same to the throwing or distributing head.

IVith the above and other objects in view, the invention consists in the novel construction, combination and arrangement herein fully described, illustrated and claimed.

In the accompanying drawings Figure 1 is a view partly in vertical section andpartly in elevation illustrating the sander of this invention. Fig. 2 is a bottom plan View of the rotary distributing head. Fig. 3 is a diametrical section through another form of rotary head. Fig. at is a bottom plan view thereof.

Referring to the drawings 1 designates a box like receptacle or reservoir for sand, the same being provided with a sloping bottom 2 in the lowest portion of which and preferably located centrally of the bottom is a discharge opening 3 with which is associated a downwardly extending sand pipe 4. The box like receptacle is shown as closed by a top or cover 5 secured or fastened thereto while the box as a whole is adapted to be fastened by means of angle irons or brackets 6 to the bottom of a motor car or vehicle.

In the preferred embodiment of this invention an electric motor 7 is mounted within the reservoir 1 but of course said motor may be mounted exteriorly thereof if preferred. ires 8 lead to and from the electric motor 7 and are connected with a switch and source of electric energy (not shown) whereby the motor 7 may be thrown into and out of operation asfound necessary. The armature shaft 9 of the motor has connected thereto by means of a suitable coupling 10 a rotary shaft 11 which extends downwardly centrally and longitudinally through the sand pipe 4: where it has fastened on the lower end thereof a rotary sanding head 12 the preferred form of which is illustrated in Figs. 1 and 2. Gentrally the head 12 is provided with an upstanding neck or flange 13 which encircles and revolves around the lower extremity of the sand pipe 4. The head 12 is shown as provided with two wings which gradually increase in width toward their outer ends where they are provided with a suitable number of holes 14 through which the sand escapes the sand being thrown outwardly by centrifugal action as the sanding head 12 is rapidly revolved by the shaft 11. In order to insure the movement of sand from the reservoir 1 to the sanding head I employ a force feed element shown in the form of an auger or spiral blade 15 encircling and fastened to the shaft 11 and located within the sand pipe 41 adjacent to the discharge opening 3 in the bottom of the reservoir 1.

Another form of head is illustrated in Figs. 3 and 4-, the same being substantially in the form of a disk 16 which is provided with radially extending ribs 17, the lower side of said head being dished as indicated at 18 thus leaving downwardly inclined bevel surfaces 19 separated from each other by means of the ribs 17.

The form of rotary head illustrated in Figs. 1 and 2 serves to confine the sand and prevent the same from being wasted, the sand being able to escape only through the holes 1 1.

In the form of a rotary head shown in Figs. 3 and 4 the sand is not confined but merely gravitates down the inclined top surface of the head and therefore there is no possibility of the sand becoming packed or congested thereon.

When the automobile is being operated on wet or greasy pavements or road beds, the operator by throwing the motor into operation distributes and scatters sand in front of the driving wheels of the machine thereby preventing the skidding of the machine and enabling the driving wheels to take a firm grip on the road surface.

It will be understood that the shaft 11 may be actuated by any other kind of motor such for example as a spring motor or said shaft may be geared. to and driven by some rotary or movable element of the motor car and equipped with means whereby said shaft 11 may be thrown into and out of operation by the driver of the machine.

\Ve claim A sander for the purpose set forth, comprising a sand reservoir, a sand pipe extending downwardly therefrom, a rotary motor driven shaft extending vertically through said reservoir and sand pipe, a rotary sand In testimony whereof we afiix our signa tnres in presence of two witnesses.
